One of the touted benefits of the Raw workflow is that you can wait to make a lot of your decisions until you process your Raw files. Although the back panel of your camera may not provide a very accurate preview, it can be improved if you do a custom white balance.

If you choose, set the in-camera white balance. This will not change any of the actual Raw data, but it can speed up processing by providing a good suggested white balance for your images when you open them in your Rawprocessing software. (Go to How to Set In-Camera White Balance)
